GMC Sierra 2500 HD
Parts fit 2001 to 2026. Owner reports cover 1996 to 2025, mapped to 2 NHTSA names, so vehicles of very different ages are counted together.
302 of 1,209 parts name an engine. The other 775 fit any, so choosing one here only narrows those 302.
What owners report
6 of 12 components, the largest by share, together 61.7% of all mentions. 1,227 reports filed with NHTSA from 1996 to 2025, read through 18 name and year queries against 2 source names. A report can name more than one component, so these 1,227 reports carry 1,480 mentions, 1.21 for each report, and every share below is of those 1,480. 140 more mentions were filed as unknown or other and are excluded from both the rows and the total.
What we can sell for it
1,209 parts from 35 brands fit this vehicle across 13 categories, and parts listed here fit model years 2001 to 2026. Suspension & Steering is the deepest at 255 parts from 8 brands. 3 of the 6 components above map to a category we stock, and the other 3 map to none.
Where the two lists meet
Each row pairs a reported component with the shelf that answers it, deepest complaint first.
Electrical System is the largest single complaint on this vehicle at 12.3%, matched by 60 parts from 10 brands.
Service Brakes are 8.6% of reports and we stock no parts in Brakes for it.
What the complaints table says
Nothing runs away with this list.
Electrical System and Power Train sit almost level at the top, with the next two rows barely a point behind.
These percentages track how often a subject came up in 1,227 owner reports filed with NHTSA, the federal body that collects vehicle safety complaints from the public.
They do not tell you how likely any of it is on the truck sitting in your driveway.
The oldest filing here dates to 1996, so many model years feed one number.
